OK, Progress Report— Both donors have swabbed their cheeks and put the samples in the return shipping packets provided.  Now we wait (a week for shipping, and 4-6 weeks for processing the samples and posting the data).
  I will post the connection or lack of when we get the data.

Since you guys have posted a couple of genealogy-related sites I will put in a comment about Ancestry.com, the outfit that does this DNA testing. I have used them several times for assistance with my Family Tree Maker Program over the past 20 years. I have always been satisfied with the responses they gave to questions.  Well this time they have really outdone themselves.  In addition to a very good oral response to my questions, they have provided automated assistance in my search for documentation of various family activities (When did great-grandfather come to the USA??) They answered with the shipping manifest for his original arrival in 1913 (a year after my Mom and her parents came) and also his passport Application in 1920 and manifests from passenger ships he used when returning to the USA from Europe in 1921, 1927, and 1931. The old guy really got around !  I would not have thought to check that, but Ancestry.com did and sent me the data !!!!!

I am pretty happy with the service I am receiving from them.
